The art and coding were obviously excellent on this, and this also has my favourite soundtrack out of the compo, and there were a lot of tracks as well! The presentation generally was fantastic. In terms of the game I played this both solo and with someone - Solo it didn't quite gel with me but I had a good time two player.
The below is all considered to be constructive so feel free to ignore it if you wish.
This is difficult to review, because it feels like you're really on to something here and when you glimpse it, it is spectacular, but we were discussing it while playing and it feels like something is missing from this version.
While we played, putting down lines or collecting food was fun but there was no threat for player 1 (the unicorn). It was like it lacked a sense of urgency. It felt like there was a twist on this where the unicorn was being actively chased, perhaps pacman style, and player 2 was blocking and/or helping them somehow, that would be extremely addictive.
Oh, and I really liked the block shapes as well, I thought they were great.
I look forward to seeing what you do further on this
